IMPROVEMENT lN PRINTERS CHASES.

Specification forming part of Letters Patent No. 206,541, dated July 30,1878; application filed May 18, 1878.

To all whom it may concern:

Be it known that I, SAMUEL ORUMP, of Mont Clair, in the county of Essexand State of New Jersey, have invented a new and useful Improvement inPrinters Chases, of which the following is a specification, referencebeing had to the accompanying drawings.

The invention relates to printers chases, and is especially designed toobviate the inconveniences that are incident to the blocking ofstereotype and electrotype plates.

It consists in the employment of an ordinary chase, in connection with aremovable bottom, arranged to fill the interior of the chase. The uppersurface of the bottom is smooth, and the plate is secured to it by meansof furniture and wedges, or in any other convenient manner, the edges ofthe plate being rectangular, or otherwise constructed, to permit of theplate being suitably fastened in place.

The details of construction appear hereinafter.

In the accompanying drawings, Figure l is a perspective view of theupper side of a device embodying the invention. Fig. 2 is a similarview, showing the under side of the same device.

A is a chase of ordinary construction. B is a bottom, which I makeremovable. The

upper surface of the bottom B is even, and occupies a plane sufficientlybelow the plane of the upper surface of the chase to accommodate theplate and to permit the insertion of the proper wedges and furniture inlockin g up the form, as indicated'with sufficient clearness in Fig. 1.

In Fig. 2 I show a movable bottom, B, which is cast or made with therectangular edges 0, and secured in place by means of the pins d, thatare passed through coincident apertures provided in the edge of thebottom and chase, as shown in said Fig. 2.

In practice, I construct the plate with rectangular edges, and secure itin place by means 7 A printers chase having a removablebottom,.substantially as set forth.

In testimony that I claim the foregoing improvement in printers chases,as above described, I have hereunto set my hand this 15th day of May,1878.
